This autumn staff from UiA have visited engineers at MHWirth to plan an outdoor test of 3D sensors developed in the project.
The test will take place during spring 2018, in the MHWirth testing tower (Kristiansand). One of the goals in the Offshore Mechatronics project is to take the research out in real life. The results will be presented at the Annual Conference May 2018.
The WP1 participated in the workshop DFP17 (Digital Fluid Power 2017) in Aalborg, Denmark, September 7-9 with all the members of the work package (Viktor Hristov Donkov, Sondre Nordås, Daniel Hagen, Torben Ole Andersen, and Morten Kjeld Ebbesen) and a guest of the WP Damiano Padovani. The workshop was dedicated to the different aspects of digital hydraulic. The workshop included 67 participants with the majority from Europe, and the industry was well represented. The WP presented two papers and received valuable feedback.

MIL and Teknova invests in a rope-testing machine to better understand how to predict remaining life of steel and fiber ropes.
“The machine lets us reproduce specific failure mode of a rope. By constantly running the rope over a sheave in a controlled environment, we are able to observe how the rope deteriorates and analyze sensor information to learn which data is important for understanding the road to failure. As a result, we will be able to predict, with greater precision, the remaining life of a rope,” says Thomas Meyer, Business Development Manager at Teknova.
The research institute Teknova, based in Grimstad and Kristiansand, is the leader of Work Package 5: Condition Monitoring Technologies in the Center for Offshore Mechatronics – an eight year long research program funded by the Research Council of Norway and hosted by the University of Agder.
WP5 aims to improve offshore maintenance operations by developing technologies and methods that enable condition-based maintenance strategies. Two of the five subtasks studies large diameter steel and fiber ropes, typical for the offshore industry.
“Our goal is to develop diagnostic and prediction algorithms that will replace human judgment by online monitoring technologies calling for maintenance weeks before failure occurs,” says Meyer.
The rope-testing machine is part of the first key equipment to be installed in the Mechatronics Innovation Lab (MIL), which is scheduled to open in Grimstad August 16, 2017.
“The machine will make MIL an interesting venue for producers of ropes and cranes. Heave-compensated cranes rely on a number of ropes that are constantly run back and forth over a sheave. A better understanding of how ropes perform over time, is of great interest and value,” says Meyer.
With a pull force of 30 tons, the 12 meters long machine manufactured in France, is designed to test ropes with a maximum diameter of 3 centimeters. Since most offshore ropes are thicker, Teknova has already applied for funding for a bigger machine, which would be able to test ropes with diameters up to 12 centimeters.
“Such a machine would be the largest in the world. It would instantly propel MIL to be an international test laboratory for offshore rope testing,” says Meyer.

Today about 30 students from a local high school visit UiA and got insight and demonstration from PhD student Sondre Sanden Tørdal of the latest work in the SFI Offshore Mechatronics project. A lot of filming went on while he did a demonstration in UiAs Motion Lab. Recruiting to engineering and science is also a focus in the project, and a lot of future students got a taste of the possibilities today.
The new Steering Board for SFI Offshore Mechatronics is the following:
- Leif Haukom (GCE NODE) Chariman
- Charlotte Skorup (ABB) Member
- Arild Strand (Bosch Rexroth) Member
- Morten Halvorsen (NOV) Member
- Michael Rygaard Hansen (UiA) Member
- Torben Ole Andersen (Aalborg University) Member
- Thomas Meyer (Teknova) Member
- Eivind Gimming Stensland (MacGregor) Deputy Member
- Torgeir Welo (NTNU) Deputy Member
Erna Solberg, The Norwegian Prime Minister, held a speech at Agderkonferansen January 24 in Kristiansand. She talked mainly about the challanges Norwegian Oil and Gas industry is facing, and that R&D must be a tool for the industry to meet these challenges. The SFI Offshore Mechatronics project is handling these issues, and the reseach done in the center will hopefully contribute to this development.
Agder is one of the regions in Norway that suffers the most of declining oil prices and lack of order reserves. This is one of the main reason for the Center to speed up and get results back to the partners as soon as possible.
